Fork and Build (Linux)

• Register with GitHub and obtained a profile. This allows the setting up of repositories where your code can be published.
• Git
• CMake

- Using GitHub and working from your main GitHub folder make a fork of DR_pi from https://github.com/Rasbats/DR_pi

- Using 'Terminal' clone the plugin onto your machine:

- Make the 'build' directory and cd to 'build':

- 'CMake' a 'CodeBlocks' project:

- To see what files have been made use 'Files' to navigate to 'learning/DR_pi/build'. The 'CodeBlocks' project is called 'DR_pi.cbp'.

- Start 'CodeBlocks' and 'Build' the project.

- There are some warnings but no errors.

- This builds the plugin file 'libDR_pi.so' in the 'build' directory

- The .so file can be moved to the plugins folder 'usr/lib/opencpn' using 'Terminal'.

- It may be easier to make a package and install this using the 'Ubuntu Software Centre'.

- From 'Terminal', in 'build', 'sudo make install', 'sudo make package'. The .deb package is made in the 'build' folder.

- Open the .deb file from 'build' in the 'Ubuntu Software Centre'.

- A warning

- Carry on!

- The plugin libDR_pi.so has been installed in '/usr/lib/opencpn'.

- When you enable the DR plugin you should see the plugin icon on the toolbar.

The next guide will show the DR_pi plugin being renamed as 'oplaydo1_pi' and modified.

'oplaydo1_pi' will allow the user to input start and finish positions. From these positions a GPX file will be created that can be imported and viewed in OpenCPN.
